Cosmo circle of the GECO team

We will have Raquel Galazo-Garcia giving a talk with the title  “Exploring Scalar Field Dark Matter Models: Analytical Insights, Numerical Simulations, and Gravitational Lensing Prospects”

The abstract is: ”

In the paradigm of the Standard Cosmological Model, 83% of the matter in the Universe is made up of an unknown substance called ‘dark matter’ (DM). However, the most favoured DM particles have still not been detected, and there are discrepancies between the predictions of the Standard Cold Dark Matter Model (CDM) and observations at galactic and subgalactic scales.
This has revived interest in alternative scenarios, in particular the possibility that DM is associated with a scalar field (SFDM).

In this talk, I will introduce the SFDM model as a viable alternative to the CDM model. Additionally, I will provide a brief overview of the analytical and numerical findings from my thesis work.
Finally, I will outline the proposed approach for my first postdoc project, which includes gravitational lensing techniques to constrain the parameters of the self-interacting scalar field dark matter model.”

The Cosmo Cirlce will take in the Mistral meeting room on the second floor at LAM.
